I'd skip iPhone and just focus on Android, mostly to save time. Browse around the iPhone app store though and find some corny apps like a fake fingerprint reader. "Steal" that idea and build an Android equivalent with mobile ads. After your first couple of apps, you could probably crank out a new one in part of a weekend. I don't know if time spent blogging about and promoting your apps would pay off when instead you could be building more apps or possibly improving the existing ones that are getting good download numbers.
